ABSTRACT: The purpose of this research was to investigate role of time perspective in prediction of students' academic achievement. In this descriptive correlation study, 380 students (188 males & 192 females) from the statistical population of students from all sections of Arak University during 2015 were selected through cluster random sampling method and filled in the questionnaire of time perspective Inventory (ZTPI-15). Academic achievement was assessed through their total score average. The results indicated that academic achievement had a significant positive relationship with future and positive past (P<0/01) and there was no significant relationship between academic achievement and other dimensions of time perspective (negative past, present-hedonistic, present-fatalist). Regression analysis showed that future, negative past and positive past could predict academic achievement among university students (P<0/01). In general, it can be concluded that students with high academic achievement consider more future and positive past, and focus less on the past negative experiences. Keywords: academic achievement, time perspective, university student
